IMPROVEMENT IN emcee.-

Specification forming part of Letters Patent No. 124,627, dated March 12, 1872.

Specification describing certain Improvements in Hinges, invented by VICTOR RATH- KNEGHT, of Chicago, in the county of Cook and State of Illinois.

My invention relates to a hinge so constructed as to be reversible and capable of being applied to the right or left side of a door or gate with equal facility; and the invention consists in making the moving leaf of the hinge-in other words, that which is attached to the door--with a recess in its face running transversely fromside to side at the upper portion of the plate; and by making the hub of a separate piece, attached to a wing which is fitted to slide. into the aforesaid recess from either edge of the plate; and the said hub is attached to the wing slightly'out of line, standing to the front, so that the hinge will close perfectly when the hub is set upon the pintle of the other plate, which pintle is attached in a direct line with the center of the other plate, so that said other plate maybe used either side out, by simply having the screw-holes reamed out upon both sides, to countersink the screw-heads.

In the accompanying drawing, Figure l is a view of the hinge with all its parts in place, and opened. Fig. 2 is a side "iew from the right hand of Fig. 1. Figs. 3 and 4 are views of the stationary leaf detached, turned to the right and left. Figs. 5 and 6 are views of the moving leaf, illustrating the manner of removin g and reversing the hub, and Fig. 7 is a section of Fig. 1 on the line 00 .90.

Like letters of reference made use of in the several figures indicate like parts.

To enable those skilled in the art to make and use my invention I will proceed to describe the same with particularity, making use of the aforesaid drawing by letters of reference.

A represents the stationary and B the moving leaf of the hinge. The stationary leaf is made in the usual manner, with an enlargement, at, extending half the length of one of its sides, from which projects the pivot 0, which stands in a line with the metal of the leaf. The moving leaf is made with a recess, 12, up-

on the upper portion of the face thereof, fitted to receive a wing, D, attached to and projecting from the side of the hub E, which is so constructed as to stand slightly out of line with the leaf when in position, after the manner of common hinges, to permit of the hinge being perfectly closed. This hub is perforated vertically to fit over and workvupon the pivot a when the parts are assembled. The stationary leaf A has its screw-holes E countersunk upon both sides of the plate, so that it may be attached either to the right or left jamb. The moving leaf B may be made right or left handed by inserting the wing D from the one side or the other of the recess I), care being always taken to turn the hub over end for end, so as to keep the alignment correct. To insure a better fit and, greater strength, the wing D and recess b are made to slide together with a dovetail joint. One or more of the screws which fasten the moving plate are made to pass through the wing D and the plate below it, securing the parts together.

I am aware that reversible hinges exist in which the hub and pintle both are made detachable from the fastening-plates; but in such hinges the hub or sliding eye is made to stand in the plane of the fastening-plate, requiring the hinge to be made in four or more pieces; whereas, by setting the detachable or sliding eye of my hinge slightly out of the plane, and by making the pintle-iu the plane of the fastening-plate, I am enabled to produce a reversible hinge consisting of only three pieces.

Claim.

The detachable sliding eye or hub E carried upon the Wing D, fitting into the recess]; of the plate B so that the hub E stands slightly out of plane, in combination with the plate A carrying the pintle c in plane, substantially as and for the purpose specified.
